Deciphering your bicycle’s issues: 5 common noises & their solutions

Bicycle Wheel

Every now and again, your bike is going to start making an annoying noise. Often the type of noise can be a handy guide to where the problem might lie and which part of your bike needs looking at. The general rule is that a silent bike is a happy bike!

Diagnosing Rattling Handlebars

A persistent rattle from your bike’s handlebars can be more than just a nuisance; it often indicates a loose headset. To confirm, apply your brakes and exert forward pressure on the bike while stationary. If the front end shakes or shudders, a loose headset is likely the culprit.

How to Fix it

Tightening a loose headset is a straightforward process. Loosen the stem bolts to allow for easy rotation of the handlebars. Gently tighten the top cap until you feel some resistance. After ensuring the wheel is perfectly aligned, securely fasten the stem bolts. If you require visual assistance, various online tutorials are at your disposal. Double-check by applying your brakes and rocking the bike forward; the juddering should have disappeared. If not, examine your bottle cage bolts, pannier mounts, and mudguard mounts, as these could also generate unwarranted noise.

Pinpointing Clicks Near Your Feet

A repetitive clicking noise emanating from around your pedals often hints at an issue with the bottom bracket. This is particularly worrisome if the noise intensifies during climbs or more strenuous pedalling. Let’s get one thing straight: this issue won’t resolve itself and will eventually make turning the pedals harder than it needs to be.

How to Fix it

Disembark and wobble the crank arms to confirm a worn bottom bracket. If you detect any movement, replacement is necessary. Modern bottom brackets usually require replacing after approximately a year, although this varies depending on the riding conditions and frequency. Consult a mechanic or your bike’s manual for replacement instructions tailored to your specific bracket type.

The Telltale ‘Swish’: Brake and Spoke Issues

A swishy noise with each wheel rotation usually implies that your brakes are rubbing against the rim, costing you both peace of mind and cycling efficiency.

How to Fix it

Adjust the brake calliper so the wheel rests squarely between the brake pads. If the problem persists, consider adjusting the brake pads themselves. If brakes aren’t the issue, inspect the spokes. Loose spokes can be another source of that swishy sound.

Chain Clunks: The Rhythm of Misalignment

A clunking sound accompanied by poor gear shifting is often a sign that your gear indexing needs attention. It’s particularly aggravating when your chain refuses to settle into the gear you’ve selected.

How to Fix it

Check your front and rear derailleurs and make the necessary adjustments. If the clunking is constant, your chain might be rubbing against the front derailleur, necessitating further adjustments. Alternatively, a comprehensive cleaning and re-lubrication of your chain might be all that’s needed to restore quiet operation.

Troubling Pedal Clicks: Time for a New Pair?

Pedal clicks can be an incessant irritant, particularly on long journeys. These noises usually indicate worn-out bearings, often exacerbated by prolonged exposure to moisture and grit.

How to Fix it

Replace your worn pedals. If that doesn’t solve the problem, you might want to examine the wheel hub, which might require servicing.

Understanding the messages conveyed by your bike’s various noises is the first step towards more pleasurable, and safer, cycling. So the next time your bicycle seems to be ‘speaking’ to you, you’ll know just how to answer.
